These breezes won’t really disrupt your plans, but you’ll definitely feel them, especially if you’re near the coast. Inland, things stay a bit calmer.
As the heavy summer rains fade, the wind direction starts to shift with the season. Coastal spots sometimes catch stronger gusts, thanks to all that open space.
Evenings bring a bit of relief, with breezes cooling things off just enough. The air stays warm, but it feels a lot more comfortable than those muggy rainy season days.
A lot of travelers actually enjoy these lighter winds—makes sightseeing and grabbing dinner outside much nicer.

As fall moves along, you’ll see winds gradually calming down, hinting that the dry season isn’t far off.
Influence of Wind on Weather Conditions
In Monrovia, fall winds shape rainfall and humidity in a pretty noticeable way. As the rainy season starts to wind down, breezes push leftover moisture inland, making heavy showers less common.
This change brings clearer skies. Humidity drops just a bit, and you can actually feel the difference.
If you pay attention, steady winds really do help with air circulation. That sticky feeling from high humidity? The wind takes the edge off, and suddenly evenings feel a lot nicer, especially if you’re out walking or hanging by the coast.
People who fish or use small boats benefit, too. The winds stay moderate, so sea conditions are usually manageable. Waves are still there, but they don’t get as wild as they do in mid-summer when those strong monsoon winds take over.
These breezes do more than just cool things off. With less moisture hanging around, you get clearer horizons. That’s handy for daily life and, honestly, makes travel planning a bit easier.
